At login, modules commands set up a basic environment for the default compilers, tools, and libraries such as: the $PATH, $MANPATH, and $LD_LIBRARY_PATH environment variables. There is no need to set them or update them when updates are made to system and application software.
From Sphyrna, users can view currently loaded modules with module list and check available software with module avail *package* (omitting the package name will show all available modules). Some modules are loaded automatically upon login:
